Abstract:
A spectroscopic assembly (165) may include a spectrometer (110). The spectrometer may include an illumination source to generate a light to illuminate a sample. The spectrometer may include a sensor to obtain a spectroscopic measurement based on light, reflected by the sample, from the light illuminating the sample. The spectroscopic assembly may include a light pipe (120) to transfer the light reflected from the sample. The light pipe may include a first opening (146) to receive the spectrometer. The light pipe may include a second opening (148) to receive the sample, such that the sample is enclosed by the light pipe and a base surface when the sample is received at the second opening. The light pipe may be associated with aligning the illumination source and the sensor with the sample.
Abstract:
In an objective optical system used for sample surface analysis by an attenuated total reflectance method by attaching to an infrared microscope, in the system including a convex secondary mirror (112) configured to reflect a measurement light irradiated from the infrared microscope, a concave primary mirror (111) configured to reflect the measurement light reflected by the secondary mirror, and a prism (138) to which the measurement light reflected by the primary mirror is irradiated, a light shielding means (140) configured to shield a part of the light beam of the measurement light is provided on an optical path of the measurement light between the primary mirror and the prism. According to such a configuration, even if there is no enough space on the front side of the secondary mirror, it becomes possible to adjust the incident angle of the measurement light incident on the prism and the sample, easily switch between the measurements which prioritizes the optical throughput and the measurement which prioritizes mitigation of the anomalous dispersion using a single objective optical system, and easily acquire a plurality of absorption spectra measured at different penetration depths.
Abstract:
The present concept is a method of preparing an egg to determine the color of the egg using an egg yolk cover (200). The egg yolk cover (200) is dome-shaped with a base edge (204) and transparent inspection area (208). The egg yolk cover (200) eliminates ambient light from impinging on the egg yolk (202) and is used in combination with a light sensor to determine the color of egg yolks (202). The light sensor includes a single flat printed circuit board with a top and bottom side which includes at least one LED light and one color sensor, at least one light pipe receiving light from the LED and transmitting it onto a substrate at an angle theta and a tube frame including an optical tube for receiving light reflections from the substrate. The light pipes and the tube frame are compression fit between the printed circuit board and a lower housing. To determine the color of the egg yolk (202), the egg is first cracked onto a flat surface (210). The egg yolk cover (200) is then placed over the egg yolk (202) and the color sensor is placed onto the inspection area (208) to measure the color.

Abstract:
This detection device has a holder and a heating unit. The holder holds a detection chip that has the following: a prism that has an incidence surface and a film-formation surface; a metal film formed on said film-formation surface; trapping bodies laid out on the surface of said metal film; and a substrate that is laid out on the surface of the metal film, and together with the metal film, forms a liquid collection section in which a liquid is collected. The heating unit heats at least one of the substrate, the prism, and the metal film either while in contact therewith or without contacting same. Also, the heating unit is positioned so as to avoid the path that excitation light takes from an excitation-light emission unit to the abovementioned incidence surface.
Abstract:
An adhering detection apparatus (101,102) includes a light source to emit probe light to a light translucent object (105) during an emission period, and to stop an emission of the probe light to the light translucent object (105) during a non-emission period, a light receiver to receive light coming from the light translucent object (105) during the emission period and the non-emission period of the light source, and an adhering detection processor (102) to perform an adhering detection processing for detecting a substance adhering to the light translucent object (105) based on light quantity of the light coming from the light translucent object (105) and received by the light receiver, and to output a detection result of the adhering detection processing. The adhering detection processor (102) selectively performs one or more processes depending on the light quantity of the light received by the light receiver during the non-emission period of the light source.
Abstract:
System and method for detecting and counting bacteria suspended in a biological fluid by means of light scattering measurements is provided. In accordance with the method of the invention the level of signal to noise of the measured intensities of light scattered by a sample of the biological fluid is significantly enhanced for forwardly scattered light within a range of scattering angles which are smaller compared to a predefined maximal scattering angle. The system of the invention includes a cuvette adapted to contain a sample of the biological fluid whose sidewalls and windows are suitably constructed and arranged to significantly reduce the level of reflected light obscuring the scattering patterns measured within the range of scattering angles considered.
Abstract:
A light guide member (220) useable for an object detection apparatus (101) is devised. The object detection apparatus (101) includes a light source unit (210), and a detection unit (206) for detecting an object adhered on a surface of a light translucent member, configuring a vehicle, based on change of light quantity of reflection light received from the light translucent member when light exiting from the light source unit (210) is reflected from the light translucent member. The light guide member (220) includes an incident face (223) where the light exiting from the light source unit (210) enters; a detection face (222) where the exiting light exits to a rear face of the light translucent member and the reflection light reflected from the light translucent member enters; an exiting face (224) where the reflection light exits to the detection unit (206); and a light guiding portion (227) through which the exiting light and the reflection light proceed. The detection face (222) has curvature corresponding to curvature of the light translucent member.
